Guys,
I picked up a shifter and the fellow I bought it from threw in a BUNCH of other stuff. The shifter has a Mychron 4 2T on it with and EGT, Water Temp, and timing sensor hooked up. That leaves the port for the expansion box open. I also got a Mychron 3 extreme with an expansion box, along with various sensors, and all sorts of other stuff. I want to use the speed sensor with the Mychron 4 2T. Is the only way to do that is to add an expansion box? If so, will the expansion box from the Mychron 3 extreme work?
Thanks,
Todd
